Description
Technical Field
[0001] This utility model relates to a connection component for a pipe joint, belonging to the field of liquid cooling heat dissipation technology. Background Technology
[0002] With the continuous development of computer technology, the power of electronic devices is getting higher and higher. Traditional air-cooled chassis and conductive liquid-cooled chassis can no longer meet the working requirements of the increasingly high heat flux density plug-in modules. Faced with the stringent space and weight requirements of data center servers, the need to achieve efficient heat dissipation within a highly integrated layout structure is becoming increasingly prominent. In order to improve cooling performance, efficient liquid cooling technology has replaced inefficient air cooling technology.
[0003] Liquid-cooled servers contain a liquid cooling loop. This loop connects to the liquid cooler in the server rack via quick-connect couplings or other types of connectors, allowing for continuous heat exchange between the server's liquid cooling loop and the external environment. Traditional connectors, being exposed to the outside, are prone to malfunctions and safety issues in complex operating environments. Utility Model Content

A receiving groove is formed on the side surface of the horizontal part of the L-shaped movable block or the inner wall of the groove. One end of the pin is embedded in the receiving groove and connected to a second elastic element provided in the receiving groove. The other end of the pin is in pressure contact with the inner wall of the groove or the side surface of the horizontal part of the L-shaped movable block.

[0029] The aforementioned receiving groove 10 is formed on the side surface of the horizontal portion 31 of the L-shaped movable block 3 facing the inner wall of the slide groove 8.
[0030] Example 2: A pipe connector assembly includes: an outer sleeve 1 and an inner sleeve 2 that can be axially and downwardly embedded in the outer sleeve 1; a horizontal portion 31 of an L-shaped movable block 3 is movably embedded in the outer sleeve 1 and can move radially; a horizontally extending first elastic member 4 is provided between the vertical portion 32 of the L-shaped movable block 3 and the outer side wall of the outer sleeve 1; a through hole 5 for the inner sleeve 2 to be embedded is provided on the horizontal portion 31 of the L-shaped movable block 3; an inner protrusion 6 is formed on the inner wall of the through hole 5 on the side opposite to the vertical portion 32; an outer protrusion 7 that cooperates with the inner protrusion 6 is formed on the outer side wall of the inner sleeve 2; the lower end face of the cooperating outer protrusion 7 and the upper end face of the inner protrusion 6 are both set as inclined surfaces extending outward from the upper end.
[0031] A horizontally penetrating groove 8 is provided on the outer sleeve 1. The two side surfaces of the horizontal part 31 of the L-shaped movable block 3 embedded in the groove 8 are each slidably engaged with the inner wall of the groove 8 by a pin 9. A receiving groove 10 is provided on the inner wall of the groove 8. One end of the pin 9 is embedded in the receiving groove 10 and connected to the second elastic member 11 provided in the receiving groove 10. The other end of the pin 9 is in pressure contact with the side surface of the horizontal part 31 of the L-shaped movable block 3.
[0032] The horizontal part 31 of the L-shaped movable block 3 is embedded in the groove 8 opened on the upper part of the outer sleeve 1; the first elastic member 4 and the second elastic member 11 are both springs.
[0033] The aforementioned inner protrusion 6 and outer protrusion 7 each extend radially; the aforementioned receiving groove 10 is formed on the side surface of the horizontal part 31 of the L-shaped movable block 3 facing the inner wall of the slide groove 8.
[0034] Working principle:
[0035] When the inner and outer sleeves separate: the vertical part of the L-shaped movable block moves away from the outer sleeve under the action of the first elastic element, so that the inner convex part on it is located at the innermost end of its stroke.
[0036] When the outer sleeve and inner sleeve are to be inserted into each other:
[0037] The inner sleeve moves downward and enters the outer sleeve. The outer protrusion on the inner sleeve moves downward with the inner sleeve until its lower end face contacts the upper end face of the inner protrusion on the L-shaped movable block.
[0038] The outward protrusion continues to move downward with the inner sleeve, while simultaneously pushing the horizontal part of the L-shaped movable block, which can only move radially, outward, so that the vertical part of the L-shaped movable block moves towards the outer sleeve and squeezes the first elastic element.
[0039] When the outer protrusion on the inner sleeve moves below the inner protrusion on the L-shaped movable block, the vertical part of the L-shaped movable block loses the restriction of the outer protrusion on the inner sleeve and resets inward under the action of the first elastic element, thereby allowing the lower end face of the inner protrusion on the L-shaped movable block to overlap with the upper end face of the outer protrusion on the inner sleeve to stop the inner sleeve.
[0040] When it is necessary to separate the connected outer sleeve and inner sleeve again:
[0041] The vertical part of the L-shaped movable block needs to be pushed towards the outer sleeve so that the inner convex part on the horizontal part of the L-shaped movable block moves outward and exits the area above the outer convex part on the inner sleeve. The inner sleeve, which has lost its stop position, moves upward under the action of the return spring, so that the inner sleeve can be pulled out from the outer sleeve. Then, the vertical part of the L-shaped movable block is released so that the inner convex part on the horizontal part of the L-shaped movable block returns to the innermost end of its stroke under the action of the first elastic element.
[0042] During the reciprocating insertion and separation process of the outer sleeve and inner sleeve, the horizontal part of the L-shaped movable block reciprocates within the receiving groove of the outer sleeve, allowing the inner convex part to move radially inward and outward. During this process, the pin block and the second elastic element provided between the two side surfaces of the horizontal part of the L-shaped movable block and the inner wall of the slide groove provide precise guidance for the horizontal part of the L-shaped movable block, preventing it from shifting its position. Furthermore, both the pin block and the second elastic element can be easily and quickly assembled inside the outer sleeve, avoiding the risks caused by exposed small parts in complex usage environments and improving the convenience and safety of use.
[0043] When using the above-mentioned pipe fitting connection assembly, it not only facilitates the assembly of each component and ensures the stability of the connection between the components, but also avoids the risks caused by the exposure of small components in complex use environments, thereby improving the convenience and safety of use.

They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
